Hi everyone! Earlier today I was viewing the Venus transit with the astronomy club at my university and I decided to try to take photos of the event through my 8 megapixel camera phone through the telescope. Of course, the quality wasn't exactly great. The last photo I took of the event was the...

Yep, I'm Australian. I certainly wouldn't wear THAT to an interview.

I went to my first job interview wearing tennis clothes and thongs, although that was only at a supermarket. I changed cities a month ago for university, and here EVERYONE seems to dress in fancy clothes, all the time. I'm getting used to wearing jeans and collared shirts when I go to lectures...

I see. I understand what you mean (as Monocles said, its a blurry line), but I think I'm a few years off from it being relevant to my studies.

Thanks everyone for the detailed replies.If I'm understanding this correctly, then mathematical physicists find out the physical implications of a set of axioms and assumptions, without needing to worry about the validity of the axioms and assumptions. Meanwhile, theoretical physicists...

Hey everyone If you want the concise version, skip over the bit in italics. First I'll quickly introduce myself. I am an undergraduate student, studying physics. I have been reading these forums for some time now (mostly just re-reading the stickies to be honest). In Australia, the first...

I was lurking around the website and stumbled across this. I don't normally care for discussions of relationships but I think you definitely need to hear what I have to say because you will only hear this from a guy, and probably only from me. Everyone else will tell you the obvious ie...

If you do Astrophysics you can do paid summer internships at the university's observatory (Stromlo from memory?) after your second/third year. I'll have to check the website, but I'm pretty sure that astrophysics was changed from a major to a specialization.

Was browsing the website and found this by chance. I'm also planning on entering ANU to study physics, finishing year twelve this year. I was at the open day a few months ago, and I was told that a) the PhB is new to ANU, only offered for the first time last year, b) you can apply to transfer...

You know when you spend ages figuring out how to do something, you are told its wrong and spend ages trying to figure out why - and when you ask for help it becomes obvious you messed up the simplest step, that's how I feel. I drew a vector diagram with the normal and its components separate...

I know that Wikipedia isn't the best source, but it was what I could find on the web to check my solution. I have been trying to calculate the maximum velocity for a car going around a banked turn. What I found online, contradicted my final equation. The following wikipedia page gives a...

Thanks. I found it was much easer to calculate the enthalpy of solution by using enthalpy of formation, and then I followed your advice.

If 5g grams Urea is dissolved in 10mL water, what is the temperature change? We are not given any constants as we are meant to research. Here is what I think I have to do: Calculate enthalpy of solution of urea. That is, enthalpy of hydration - lattice energy of urea. Then I multiply this by...
